You're right, and for player/custom character creation, I will almost certainly implement a single hairstyle list in that particular update. Especially as it'll include nonbinary and trans options.
Will the player be able to be nonbinary or trans after they started the game as male or female,also it would be cool if the trans characters as a affinity high enough or when you have sex,they would tell you that they are trans or a trans man would refuse to go to the beach without a shirt,because of the top scars from surgery.
